ROBERT V. GORMLY, OF TROY, NEW YORK.

BURR-WHEEL FOR KNITTING-IVIACHINES.

SPECIFICATION forming part of Letters Patent No. 375.351, dated December27, 1887.

Application iiled September 20, 1886. Serial No. 214,095.

(Model.)

To all whom it may concern:

Be it known that I, ROBERT W. GORMLY, of the city of Troy, in the countyof Rensselaer and State of New York, have invented certain new anduseful Improvements in BnrrfWhee'ls for Knitting-Machines, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which- Figure l is an axial section of my improvedburr-wheel. Fig. 2 is a view of a portion of the burrdisk. Fig. 3 is aside view of the bushing and the supporting-plate of the burr. Fig. 4 isa detached View, in vertical section, of the oil-chamber (seen in Fig.l) and its cover. Fig. 5 is a side view ofa burr-wheel, showing aburr-disk of my improved construction employed in connection with an oldform of securingnut and an old form of oil-chamber.

Like parts are marked by the same letters in dierent figures.

My invention consists in making the oper-l ative portion of theburr-wheel in one piece,

as a disk having wings or iiukes cut therefrom and bent or twisted tothe angle required for the operations of a knitting-machine, and in thecombination,with the upper end of the bushing of the wheel, of an oilreservoir or chamber, from which oil may pass through apertures in thebushing to lubrieate the ordinary bearing.

In carrying out my invention I take a circular blank having a centralopening, I-I, and of the desired sizeof annealed steel and cut into itsperiphery to suitable depths and at regular spaces, thereby forming theblanks for the wings h continuous with the body H of the disk. Thesewings after being out or liled to proper form are then twisted to acertain angle or placed under a metallic die, by which the wings arestamped or pressed into such an gular forms as are necessary to adaptthem to operate with the needles in the usual manner. I also cast orform an ample oil-reservoir, E, of suitable metal, having threads c' onits inner surface at the top, in which is screwed the cap e, and alsohaving interior threads, e?, in its base to match with the threads e3.(Seen on the bushing A in Fig. 3.) The said bushing has a centralopening through its entire length, suitable apertures, a', being made topermit oil to pass from the oil-chamber into the bushing to lubricatethe bearing-surfaces. I place upon the shoulder a of bushing A thesupporting-plate D, and then the burr-disk H', upon which I drop anannular packing, P, which prevents the escape of oil. I then screw theoil-reservoir E into position, as seen in Fig. I, and pour in the oil tonearly the height ofthe bushing and above the apertures a', one or moreof which are extended to nearly the bottom of the oil-chamber. I thenscrew down the cap c to near the top of the bushing, as seen in Fig. I,or, as I prefer, on the top of said bushing A, which is thus covered, orthe same may be closed with a suitable packing, i, to prevent any oilreaching the bearing'snrfaces except through the apertures a.

When my improved burr-wheel is placed upon the ordinary bearing-pin, B,a portion of which extending above the oil-apertures is seen in Fig. l,my device may then be used in the ordinary manner in knitting fabrics.

My burr-disk may be used not only with my improved oil-reservoir, asseen in Fig. 1, but also as seen in Fig. 5, where in place of myoil-reservoir a nut, F, is screwed down upon the bushing to secure thedisk I-I, while from the oil-cup C, secured on the bearing-pin B or itssupporti 11g-arm, or lower end of the bushing, the oil lubricates thebearing-surfaces; and it also may be used in place of all the ordinarycircular burrs employed in knitting.

What I claim, and desire to secure by Letters Patent, is-

' 1. A knitting-burr disk having theperiphery thereof cutinto divisionsof uniform depth and width, and said divisions bent to form wings,substantially as described.

2. An oil-reservoir, E, placed upon the upper end of the aperturedbushing, in combination therewith and with the compressible packing I?,the disk II', supporting-plate D, and bearing B of a knitting-burr,substan tially as described, and for the purpose set forth.

ROBERT V. GORMLY.
